In the construction of modern cities, perfect drainage engineering facilities involve numerous drainage and sewage pipeline systems. At present, the construction of drainage pipeline network in my country is still relatively backward in some aspects. The current situation of municipal drainage pipelines in my country will be introduced later. The collection, transportation, purification, utilization and discharge of urban domestic sewage, industrial wastewater, atmospheric precipitation, snow runoff and other waste water are all drainage works. Urban drainage facilities include pipeline networks for collecting and conveying urban drainage, pumping stations, as well as sewage treatment plants and final sludge disposal and related facilities. Urban drainage engineering is an indispensable and important infrastructure for modern cities, a basic industry that has an overall and leading impact on urban economic development, and a backbone project for urban water pollution prevention and urban waterlogging, waterlogging, and flood control. Urban drainage facilities are an important symbol to measure the level of a modern city, an important link to improve the urban investment environment, and play an important basic guarantee and leading role for urban and social and economic development. Drainage pipes are an important part of drainage works.
At present, the current status of municipal drainage pipes in my country is as follows: the demand for municipal drainage pipes is increasing; the renewal and reconstruction of municipal drainage pipes. At present, this renovation has entered the peak period; the construction of the rainwater collection pipe network will continue to increase the demand for drainage pipes. Practice has shown that rainwater collection, treatment and utilization is an economical way to draw water. my country is a country with a serious shortage of water resources. The north, especially the northwest, has the most serious water shortage. The collection, treatment and utilization of rainwater will alleviate its serious water shortage problem.
